IMPROVEMENT IN COMBINED PERFORATING AND CANCELING STAMPS.

Specification forming part of Letters Patent No. [80,309, dated July 25, 1876; application filed December 30, 1875.

To all whom it may concern:

Be it known that I, CHARLES ARMSTRONG, of Chicago, in the county of (look and State ofIllinois, have invented certain new and useful Improvements in Canceling-Stamp, of

which improvements the following is a full, clear, and exact description, which will enable others skilled in the art to which my invention appertains to make and use the said improvements, reference being had-to the accompanying drawing, forming a part hereof, and in which- Figure 1 is a side elevation of a double can.- celing-stamp embodying my invention; Fig. 2, a like representation of a single stamp, also embodying my invention; Fig. 3, a vertical central section of thesinglc stamp; Fig. 4, a face elevation of the double stamp.

Like letters of reference indicate like parts.

The object of my invention is to make a hand canceling-stamp whereby postage-stamps, envelopes,.newspapers, commercial paper, and

the like may be canceled with facility by means of ink impressed thereon, and also by puncturing or perforating the same, both by the same-act or operation.

To this end, my invention consists in certain details of construction, as hereinafter specified and claimed.

In the drawing, A represents the handle of the stamp and B is a metallic die, attached to the handle, and having on its lower face the perforating points or disks a a. O is a yielding die or blotter, made, preferably, of rubber, and adapted, on its lower face, to im-' print a canceling-mark to whatever it may be applied for that purpose, it being understood that the lower face of the part G is first suitably inked. I

The lowerface of the die 0 extends a little way below the lower face of the die B, as

shown in Fig. 3, so that the die 0 will strike the object to be canceled at about the same time the perforators a a do, and then yield Sufliciently to allow the perforators either to pass through or break the paper to which the These perforators may be projections, having flat faces or disks; and I be effa-ced.

deem the latter construction preferable for most purposes.

The die 0 is prevented from being pushed upward out of place when the blow is given, by means of a shoulder formed by the handle, as shown.

The device shown in Fig. 1 is, in its general appearance, the same as those heretofore employed in post-offices for the purpose of canceling the stamps on letters and newspapers, and at the same time indicating, by means of the die or stamp D, the office from which they are mailed, but differs in construction from the said stamps, in the fact that my improved canceler, hereinbefore described, is

applied thereto in the place of theordinary stam'p-canceler or die. This attachment I make by screwing the die B into the bar E, and by arranging the die 0 on the die B, as already described; and for the purpose of rendering this canceling-stamp capable of be-' ing transferred with facility from the single stamp or die to the double one, and vice.

versa, I also screw the die B into-the handle of the single stamp, as shown in Fig. 3.

To make this stamp more durable, I employ the metallic thimble F, arranged on the lower end of the handle, as shown.

In Fig. 3 the part 0 is represented as surrounding the die B.

The advantage of the combination of the yielding die with the perforating die or disk is, that the letters, papers, and stamps will be more effectually canceled, and the stamps, for example, even though the ink be removed, will plainly appear to have been once canceled, for the perforations will remain, and the appearance thus given cannot afterward with perforators, and arranged relatively to v the yielding die, that the lower faces of the duplex die shall be practically on the same plane, substantially as and for the purpose .In Witness whereof I have hereto set my set forth. hand this 24th day of December, A. D. 1875.
